U.S. Optics SR-8c: Test 2 Results

Box Drill

As I described before, this test uses directional transitions to test the friendliness of the optic to target acquisition.  Two target stands are placed approximately 7 yards apart.  Each target stand is 8′ tall and has a target at the bottom and a target near the top.  The shooter stands equidistant from each stand so that they are both approximately 10 yards from the shooter.

The directional order of engagement is :

1. Start at the top left target.
2.  Right
3.  Diagonal, down/left
4.  Up
5.  Diagonal, down/right
6.  Left
7.  Diagonal, up/right
8.  Down
9.  Diagonal, up/left

If everything goes correctly, the result is three shots on the upper left target and two on each of the others.  The first shot acts as a “zero” point since a transition is really what happens between shot and I was measuring 8 directional transitions, which means I needed 9 shots.  I fired this course of fire 4 times with each optic.  This was the first time I had ever shot this drill, although approximately 2 months earlier I had practiced it in dry fire sufficiently to get the rather complex pattern down.

I used the same targets for all four runs, pausing between to take a photo so I could deduce what hits came from which run.  What I could not tell was which hits come from which individual shots within a run, which would have been interesting as well.  Here are the targets after the entire four runs were shot.

Here are the average shot times from all four runs:

1.  1.26
2.  1.37
3.  1.25
4.  1.23
5.  1.36
6.  1.45
7.  1.29
8.  1.09
9.  1.36

Total Average time: 11.65
Total Average Points: 43.75
Average points per shot: 4.86
Average Hit Rate: 89% (40/45)
Average hits per second: 0.69
Average Points per Second: 3.75

I think a clean run in 9 seconds (or equivalent score, 1 hit/second or 5 points per second) would be about the minimum acceptable standard.  As with the previous test, my own performance goals really have nothing to do with the optic, and this is a baseline.  Plus, it doesn’t bother me either way.

Thanks for reading.

  1. On a scale of 1 to 10, 1 being not dizzy at all and 10 having difficulty standing, I would say a 1.

    • I’m in awe. I got dizzy just trying visualize your movements.
      Or maybe it was the Pinot Noir…

      • Just take it one shot at a time. It’s not as bad as it looks. The sequence is all clockwise, but there’s no sensation of going in a circle because each shot is a punctuation. Then you can think of it as a series of triangles that roll through the target array. I did get confused for at least one shot in the last two times I did this test. That shows up as a 1.5-1.8 second split when there should be something closer to 1. It feels like it should be a three second split because there are so many different mental things going on. The one bad split is offset plenty by the other 35, so I don’t sweat it.

        It was probably the Pinot.
